摘　　要：综合考虑当前工序机器状态和上游工序来料质量,利用马尔科夫模型,根据合并迭代的思想建立了关联多工序制造系统的加工质量分析模型,提出了系统质量瓶颈加工工序的判定方法,从系统参数的角度提出了改进加工质量的建议;同时,通过对国内某型号火箭F系列阀门壳体加工系统的案例分析,验证了所提出模型的实用性和有效性.In manufacturing systems, the complex parts like astronautical valve are often processed through several correlated stages. It is absolutely of great importance to evaluate and analyze the quality of such correlated multistage systems. This paper, based on the Markov chain method and incorporating iteration, presented an analytical model to evaluate the quality of the correlated multistage system. The model took machine states as well as the quality of the incoming parts into consideration. It emphasized the quality propagation between adjacent stages, revealed the quality changes after each stage and proposed to improve the quality of the final product from the aspect of the parameters of the processing machine. The effective- ness of this model was validated by a case of multistage manufacturing system of astronauticalvalve used in a domestic rocket manufacturing company.
